I've been using this 32oz bottle daily for about a month now and it's become my go-to. The 316L medical grade steel interior gives me confidence it won't retain flavors, and after rinsing it out there's no lingering taste from yesterday's coffee. The leak-proof claim holds up — I've tossed it in my bag sideways without a single drop escaping. Ice still rattles around after a full day at my desk, and the lid comes apart easily for a proper clean, which matters more than I expected. The fire extinguisher shape is a fun touch and the built-in straw makes sipping effortless.
